Our 2003 Mountaineer sits all day outside my wife's work. Often she can't get into the vehicle after a day sitting outside in the freezing weather. She notes that fellow employees seem to not have this problem. I sprayed the locks with WD 40 but it doesn't help. Any other tricks that might help here. This was not a problem until this year.
You don't really give enough info for people to help. What part is affected - the key is stuck?, the keyless entry doesn't unlock?, the door handle is stuck, does the power lock move the lock plunger properly?
Locks can fail in many ways but the key is to lubricate them -- including the door latch on the side of the door. Not sure WD-40 is the best for this long term but it should help...
I had a door latch fail on mine that caused a door to not open sometimes - little spring in the latch itself had broke.

We only get a hand full of frozen days but I just leave my door unlocked if its going to be freezing rain, as for WD-40 thats no good for locks, use some contact cleaner to get it all out, let the contact cleaned evaporate out of your locks then use powdered graphite.
